Abstract

The additive described essentially comprises a selected alkoxylated fatty amine or fatty amine derivative and a special metal salt compound, preferably a metal soap. This additive for heavy oils effects a good emulsification or dispersion of asphaltenes and other higher-molecular weight compounds and, in addition, inter alia, increased storage stability, improved pumpability due to decreased viscosity of the oil and longer service lives of the filter systems. In addition, it also effects enhanced combustion of the heavy oils. The effective amount of additive in these oils is 2 to 2000 ppm. The oils described are suitable, in particular, as furnace fuel for industrial plants and power stations and as engine fuel for marine engines.

Description

The heavy oil of improved performance and the additive that is used for heavy oil
The heavy oil that the present invention relates to improve the additive of performance of heavy oil and contain this additive.
Heavy oil obtains in petroleum-type (crude oil) processing, and is for example resistates in normal atmosphere or very aerial distillation, thermo-cracking or catalytic cracking etc. of the course of processing.From the angle of chemistry, fuel that these are remaining or remaining power fuel (" C " number heavy fuel oil) are made up of paraffinic hydrocarbons, naphthenic hydrocarbon and the aromatic hydrocarbon of part macromolecular structure basically.This high molecular component is also referred to as bituminous matter, can not exist with the dissolved form, but can exist with discrete form more or less, causes many problems thus.Therefore, bituminous matter and similar other poorly soluble or insoluble compound (for example oxygen compound, nitrogen compound and sulphur compound) and ageing products can be isolated from oil phase in the presence of no effective dispersion agent, form undesirable especially two phase systems.In addition, in the presence of water, even only in the presence of moisture, can form slurry equally.In addition, all these macromolecular compounds in the heavy oil and composition have a negative impact to the combustion processes of oil, for example cause forming a large amount of carbon blacks.
Heavy oil, particularly exist with the form of mixtures of heavy fuel oil (HFO) (marine fuel oil) form and heavy fuel oil (HFO) and last running (Inter oil fuel), main in large quantities as the use of the fuel in full scale plant and the power station, and as the slow relatively particularly motor spirit use of marine engine of oil engine of burning.Therefore, in the prior art, various additives have been proposed to use, by using these additives can eliminate the unfavorable performance of described heavy fuel oil (HFO) and dynamic fuel oil, particularly form the formation of two phase systems, slurry and to the incendiary disadvantageous effect because of bituminous matter and other macromolecule component.
Therefore, FR-A-2172797 has described organic acid alkali formula molysite, the mixture that FR-A-2632966 has described ironic hydroxide and alkaline calcium soap as auxiliary agent to improve the burning of heavy oil.The US-A-4129589 suggestion uses the magnesium salts of high alkalinity and oil-soluble sulfonic acid as oil additives.Nearest disclosed EP-A-476196 has described a kind of mixture as oil additive, it mainly comprises (1) at least a oil soluble manganese carbonyl compound, the organic acid alkali metal salt of (2) at least a oil-soluble neutrality or alkalescence or alkaline earth salt and (3) at least a oil-soluble dispersant that is selected from this group of being made up of the succinimide class.In addition, equally also can mention US-A-5421993, it has described the derivative that uses oxyalkylated fatty amine and fatty amine inhibiter, demulsifying compound and the pour point reducer as crude oil.
The mixture that has been found that oxyalkylated fatty amine compound and organic metal salt now is effective especially additive for heavy oil, particularly with regard to emulsification and dispersed bitumens matter, slurry etc. and the oily aspects such as burning of improvement.
